A new study finds that fast food causes high blood pressure. Study participants who ate low-fat, high-sugar meals (like Fruit Loops and Sunny D) didn’t see their blood pressure spike the way that participants who ate burgers and fries did. The study concludes that it must be the fat in the food causing the immediate dangerous spike in blood pressure. It’s “food for thought” (sorry), but we’d be very curious to know if the researchers also measured blood sugar levels immediately following the meals. We’re willing to bet that both groups, but especially the low-fat group, saw a big blood sugar roller coaster after tucking into the 800+ calorie meals.

You all know we are seriously pro-fat around here. We don’t espouse the popular 90s trend of low-fat everything, generally because low-fat foods are often very high in sugar, which is devastating to health. Fat is good for you. We’re not saying fat needs to be your BFF*, but without natural fats in your diet, you’re at risk for stress, depression, anxiety, unhealthy skin, Alzheimer’s, improper nutrient absorption…well, it goes on and on! However, there’s a world of difference between natural, essential fats and processed, refined greasy fast food, as this study shows.
